EXTINGUISHING DEVICE.

SPECIFICATION forming part of Letters Patent No. 225,350, dated.March'Q, 1880.

Application filed September 4, 1879.

Fig. 4 is a detail view of the wick-wheel-raising device. l

Similar letters indicate corresponding parts. My invention relates toinstrumen tsfor lighting and extinguishing lamps or gas-lights locatedbeyond convenient reach; and it consists in the combination of a benttube, a cylinder attached to one end of such tube, a springimpelledpiston fitted into the cylinder, and its rod, for the purpose ofproducing an air-blast and directing such blast upon a flame.

In the drawings, the letterA designates the bent tube; B, the cylinder;C, the piston; l), the piston-rod E, the taper-holder F, the wick-wheelsocket, aud G the gas-cock key.

The bend in the tube A is near its upper end, and the cylinder B isprovided with two heads, I1, h, one at each end, by one of which it isattached to the lower end of the tube.

rlhe piston C is fitted into the cylinder B and subjected to the actionof aL spring, ,having a tendency to impel or force the same' in anupward direction, while the rod D serves to retract the same against thespring. This rod D extends through the lower head, h, of the cylinder,and is bent at the outer end, so that it may be conveniently taken holdof'.

If the piston C is drawn back and then released, the air in the tube Ais thereby compressed and a blast of air is ejected from the outer orfree end of the tube, so that if this blast is directed upon a flame byholding the tube accordingly the flame is extinguished.

It will be seen that the piston and cylinder constitute a very effectiveair-compressing devic, and one which is extremely durable.

The taper-holder E consists of a tube open at both ends, and is attachedto the upper or free end of the tube A, the same being curved gitudinalribs, l.

away from the tulle A at its extremity, where it projects, as shown. Bythis arrangement of the taper-holder E it is adapted for lighting a lampor gas, while it does not materially increase the size of theinstrument.

rlhe socket F projects from a straight portion of the tube A, and has aconical or daring.

shape, while it is provided with internal lon- By placing the socket Fover the head'ot` a wick-raising wheel upon a lamp the ribs L engagesuch head, so that the wheel can be turned to raise or lower the wick bya corresponding motion of the socket, and, owing to its peculiar shape,the socket is adapted to wick-wheels of any usual size.

The key Cr is situated at the top of the bend in the tube A, and has aforked shape, so that it may readily be adjusted over the key of agas-cock for opening or closing the latter.

I am aware that it is not new to combine with a bent tube anair-compressing device consisting ofan elastic bulb; noris it new,broadly,

to combine a taper-holder with a bent tube and air-compressor. Such notbeing within the scope of my invention, I hereby disclaim the same.

What I claim as new, and desire to secure by Letters Patent, is-

l. The combination of a bent tube,` a cylinder attached to one end ofsuch tube, a springimpelled piston tted into the cylinder, and its rod,for the purpose of producing an air-blast and directing such blast upona name, all constructed and adapted for use substantially as described.l

2. The combination, with a bent tube, A, and air-compressin g device,ofthe taper-holder E, composed of a tube open at both ends, secured tothe upper free end of the bent tube parallel therewith, and curved awayfrom the extreme end of the said bent tube, substantially as described.4 In testimony whereof I have hereunto set my hand and seal this 2d dayof September, 1879.
